Pure poliurea vs hybrid on roofs
Notas de ingeniería. No un blog. Keep pure poliurea vs hybrid as separate names. Poliurea Rayston (pure poliurea) is the pure proyectado en caliente. Impermax Poliurea H (proyectado en caliente hybrid poliurea) is the hybrid. Therefore do not collapse H, H Flex and Rayston into one generic poliurea.
Marks that keep pure poliurea vs hybrid apart
Poliurea Rayston carries CE EN-1504-2, ETA ETAG005 16/0148, BBA 18/5582 and WRAS in Catalogue 2024. Impermax Poliurea H carries ETA 11/062. Impermax Poliurea H Flex carries EAD-030675 21/0740 for bridge decks. Impermax Poliurea H Supreme and Impermax Cold Poliurea Supreme carry CE EN-1504-2.
Cubiertas de aeropuertos, car-park roofs and pedestrian roofs may schedule more than one of these. The application page is the schedule. Poliurea en frío (ETE 17/0509) is a third family. It is not a proyectado en caliente. It is not Impermax 1K. Use the name printed on the card.
However, a UV finish is still required where the catalogue says so. Rayston Fire E is a bleacher membrane, not a generic roof finish. Also, read consumo from the current TDS, then the calculadora.
Cómo redactar the two names
First, write the commercial name. Then write the chemical type in the same sentence. After that, cite only the mark Catalogue 2024 prints on that name.
See Poliurea Rayston, Impermax Poliurea H, and airport roofs.
Outbound reference: BBA — British Board of Agrément.
A generic poliurea line on a drawing is not a specification. Write the commercial name.
Therefore the current TDS remains the source for mix ratio, overcoat and consumo. Then the calculadora sizes the area. However, a number invented here would be a specification error. In addition, the application page is the schedule. First name the exposición. Next name the commercial product and the chemical type in the same sentence. After that, open documentos. Also keep the finish on the same clause as the body. A sample, a colour or a photograph does not replace that sentence.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the current sheet, then the calculadora.
